Budapest tram

Budapest public transport is provided by BKV, the company operates buses, trolleybuses, trams, suburban railway lines, the metro, a boat service, a cogwheel railway and a chairlift, called Libegő.
Budapest's tram network is extensive, and reliable despite poor track infrastructure and an ageing fleet. Routes 4 and 6 combined form the busiest traditional city tram line in the world, with the world's longest passenger trams (54-metre (177 ft) long Siemens Combino) running at 60 to 90 second intervals at peak time and 3–4 minutes off-peak and usually packed with people.
